<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I'll try explain my situation:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I created a RRD file using this
command:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>rrdtool create test1.rrd --step 300
\<BR>DS:bitsIn:DERIVE:600:0:U \<BR>DS:bitsOut:DERIVE:600:0:U
\<BR>RRA:AVERAGE:0.5:1:800 \<BR>RRA:AVERAGE:0.5:6:800
\<BR>RRA:AVERAGE:0.5:24:800 \<BR>RRA:AVERAGE:0.5:288:800 \<BR>RRA:MAX:0.5:1:800
\<BR>RRA:MAX:0.5:6:800 \<BR>RRA:MAX:0.5:24:800
\<BR>RRA:MAX:0.5:288:800</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I have many files in server, one by customer. I
have some scripts wich create and update then (is not the case). Since 2 years
ago, its work perfectly, showing day, week, month and year graphs.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Howerver, now, i need to keep last 180 days, in 5
minutes resolution, in this files.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I simply run this command:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>rrdtool resize test1.rrd 0 GROW 52768</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>This command, sets 53568 rows for RRA
0.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>So the rrd file, is now, have the
format:</FONT></DIV>
<DIV> </DIV>

<DIV><BR>The big problem:</DIV>
<DIV> </DIV>
<DIV>Before the resize, when i run "rrdtool fetch test1.rrd AVERAGE -r 1800 -s
-1w", returns:</DIV>
<DIV> </DIV>
<DIV>1284057000: 3.4084031790e+04 2.6132590178e+05<BR>1284058800:

3.2887164485e+05<BR>1284062400: 5.8641710980e+04 2.3696226381e+05<BR>1284064200:
3.8370010026e+04 1.8178822367e+05<BR>[...]</DIV>
<DIV> </DIV>
<DIV>Note that resolution is 1800, wich the diference between the timestamps.
Therefore, when i generate the graph, it show correctly.</DIV>
<DIV> </DIV>
<DIV>AFTER RESIZE, when i run "rrdtool fetch test1.rrd AVERAGE -r 1800 -s -1w",
returns:</DIV>
<DIV> </DIV>
<DIV>1284056400: nan nan<BR>1284056700: nan nan<BR>1284057000: nan
nan<BR>1284057300: nan nan<BR>1284057600: nan nan<BR>[...]</DIV>
<DIV> </DIV>
<DIV>Note that resolution, even forced resolution with "-r 1800" the fetch
returns rows with resolution of 300 seconds between rows. Therefore, when i
generate the graph, it is shown wrong, only last 2 days.</DIV>
<DIV> </DIV>
<DIV>What may be happening? Help me!</DIV>
